1.数字滤波器简介模拟滤波器的输入和输出都是连续信号,要想改变滤波器的频率特性一般是改变硬件电路。数字滤波器的输入和输出都是数字信号。图1是这两种滤波器的原理框图。
1. Digital Filter Introduction Analog filter input and output are continuous signal, in order to change the frequency characteristics of the filter is generally change the hardware circuit. Digital filter input and output are digital signals. Figure 1 is a block diagram of these two filters.
